, SPECIFICATION form g part of Late. Patent No. 413,966, dated. October29, 1889.

' V Application filed February 15, 1889- Seiial No. 300,021. (No model.)

Be it known that I,'AI.1 HoNso RIGGS, a citizen of the United States,residing at Cincinnati, in the county of Hamilton'and State of Ohio,have invented certain new and useful Improvements in Window Screens; andI do declare .the following to be a fuILcle-ar, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of My invention. relatestowindow-screens 7 used for the purpose of excluding insects from theinterior of houses; and it consists in the novel arrangement andcombination of i the difierent parts, as described and pointed out inthe specification and claims, and as illustrated in the accompanyingdrawings, in

' which- Figure 1 is an inside view of a window, the

lower sash partly raised. Fig. 2 is an upright cross-section of thesame. Fig.3 is a hori- 4 is a vertical longitudinal section of theroller-box. Figs. 5 and 6 are enlarged cross sect-ions'of theguide-casing.- Fig. 7 is an enlarged view of the adjustable bearing 22,parts of casing 16 broken away to show slot 24.

7 is'the sill, 8 the lower and 9 the upper sash, and 10 the box-frame.

11 is the screen connected to the sash by a strip 12.

13 are the rollers, 14 grooved pulleys secured to their ends, and 15 arethe roller-boxes.

16 are casings=two to each sash.

17 are pulleyswe to each casing, and

being opened and is hinged to the stationary parts of the casings 16. InFig. 1, to the left, part 19 is omitted to show inside of easing. Thishinged part is ordinarily kept closed toward the stationary part bysprings 20. (See Fig. 6.) 21 are screws by which the casings are securedto the woodwork. The journals roller 13 from turning within each other,Iuse a well-known device, which consists 1n closes the opening.

ATE-NT- OFF C of. the pulleys 17 are secured in a sliding beaia ing 22,which in turn connects to a spiral spring 23, by means of which theendless chains or The journals also Figs. 2 and 7) in the casings, inwhich they slide, and whereby the pulleys are kept in their properposition i 25'is a screw passing through the upper end of the casing, towhich the spiral spring 23- connects, and by means of which the tensionof the latter may be properly regulated. 26 is a connecti0n-one securedto each sash-passing between the stationary and yielding parts of thecasing to the cord-18, (see Fig. 5,) to which it is rigidly connected.In order to make roller 13 and its box or casing 15 adjustablelengthwise, they are made each in two sections, one section being partlyreduced near its end and sliding within the other like in a telescope,as clearly shown in Figs. 1, 3, and 4. To prevent the sections ofproviding one section with a groove and the other with a feather whichslides in the groove of the former section, as shown at in Fig. 4. Toremove the roller, nut 27 is unscrewed and the roller pushed togethertill one journal clears its bearing, when it may be readily taken out.To-put it in position again after the box is adjusted, it is extendedinthe latter until its journals have entered their respective bearings,when they are secured therein by means of nuts 27.

28 are lugs by means of which box 15 issecured to the sill.

29, in Fig. 3, are the sash-weights.

The operation of the parts is as follows: One of the sashes beingopened, the screen, being connected thereto, of course follows and Thesash being closed and connection 26 secured to it, the endless chain orcord 18 revolves theroller 13 by means of its pulleys 14, around whichthe cord 18 passes, and thereby winds the screen up and around theroller. The screen is so wide as to reach into the casings 16, which, in0011- junction with hinged part 19, form a guide for the screen. Thishinged part is yielding and adjusts itself to the thickness of thescreen, being kept bearing against it by springs 20, (see Figs. 5 and6,) and thereby prevents the screen from flapping.

If a chain is used in place of a cord 18, sprocket-wheels may besubstituted for the pulleys 14 and 17. For the upper sash theattachments may be secured on the outside of the same.

I claim as new and of my invention 1. The combination of a'sash, ascreen connected thereto,a roller 13, to which the other end of thescreen is connected, pulleys 14, secured to the ends of roller. 13,pulleys 17, secured in a Vertical plane with the former but a distanceremote therefrom equal to a little more than the movement of the sash,as shown, an endless chain or cord passing around pulleys 14 and 17 anadjustable spring-actuated bearing 22 23 25, in which roller 17 revolvesand whereby the endless cord or chain is kept taut, and a connectionfrorn sash to the cord, whereby cord, pulleys, and roller 13 areoperated, as shown and described.

2. The combination of a sash,a screen connected thereto, an adjustabletelescoping roller 13, to which the other end of the screen connects,pulleys 14, secured to the ends of roller 13, pulleys 17, secured in avertical plane with the former but a distance remote therefrom equal toa little more than the movement of the sash, as shown, an endless chainor cord passing around pulleys 14 and vertical plane with the former buta distance remote therefrom equal to a little more than themovement ofthe sash, as shown, an endless chain or cord passing around pulleys 14and 17, an adjustable spring-actuated bearing 22 23 25, in which roller17 revolves and whereby the endless cord or chain is kept taut, aconnection from sash to the cord, whereby cord, pulleys, and roller 13are 0perated, and yielding guides to either side of the screen to keepthelatter straight, as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
